Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] The structural diagram of the charging gun locking device used in pure electric buses is shown in figure 1 As shown, the locking device includes a battery management system, an electronic lock unit, a first relay a and a second relay b. Wherein, the electronic lock unit is installed on the charging socket, including the motor M and the position switch. One end a1 of the coil of the first relay a and one end b1 of the coil of the second relay b are respectively connected to the first control terminal Pin1 and the second control terminal Pin2 of the battery management system, and the other end a2 of the coil of the first relay a is connected to the second control terminal Pin1 of the battery management system. The other end b2 of the coil of relay b is grounded. The normally open contact a5 of the first relay a and the normally open co...

Abstract

The invention relates to a charging gun locking device for charging equipment, which comprises an electronic lock unit and a processing unit used for detecting the start and end of charging, wherein the electronic lock unit comprises a motor. The locking device further comprises a motor forward rotation control circuit used for locking a charging gun and a motor reverse rotation control circuit used for unlocking the charging gun. The processing unit is connected with the motor forward rotation control circuit and the motor reverse rotation control circuit. The charging gun locking device effectively avoids the occurrence of an arcing phenomenon caused by mistakenly pulling the charging gun in the charging process of the charging gun, and ensures the personal safety of the charging personnel.

Description

technical field [0001] The invention relates to a charging gun locking device used for charging equipment, and belongs to the technical field of pure electric bus charging. Background technique [0002] On pure electric buses, vehicle charging is an essential and common function. With the development of charging technology, high-current fast charging has been gradually applied. Unplugging and inserting the charging gun during the charging stage will cause arcing, which will cause great harm to people and vehicles. [0003] At present, most of the buses on the market do not realize the automatic locking function of the charging gun during the charging stage. Therefore, how to avoid the phenomenon of arcing caused by mistakenly plugging and unplugging the charging gun during charging, and prevent the accident of live plugging and unplugging safety accidents. occur and become an urgent problem to be solved. Contents of the invention [0004] The object of the present invent...
